Korg SQ-64
The SQ-64 is an enthusiast-tier polyphonic step sequencer with no keys of its own, built to drive hardware. With USB, MIDI DIN, and true CV/Gate output, it's aimed squarely at hybrid and modular rigs that need to sequence Eurorack and CV synths together. It's a focused tool: useful only if you already have hardware or a modular setup to control.

Verdict
Best for
- hybrid and modular setups
- polyphonic step sequencing
- driving CV/Gate hardware synths and Eurorack
Who should skip this
- Live keyboardists — it's a step sequencer with no keys for real-time playing
- All-software producers — its CV/Gate strengths are wasted without hardware synths or Eurorack
- Beginners wanting a simple controller — its polyphonic step workflow has a real learning curve
